A new action group was announced in Dubai on Saturday to help Commonwealth countries, rapidly cut emissions of methane as part of wider efforts to keep rising global temperatures within liveable limits.
The country-led coalition was announced at a ministerial event on the margins of the United Nations Climate Change Conference (COP28).
Methane, the main greenhouse gas after carbon dioxide, is responsible for more than a third of the current global temperature rise.
A reduction of 45 per cent by 2030 is necessary to keep the Paris Climate Agreement's target of limiting global heating to 1.5 degrees Celsius within reach.
The action group will be made up of Commonwealth countries and partners committed to sharing knowledge, expertise, technology, and policy solutions to reduce methane emissions and effect broader positive change.
In announcing the action group, Commonwealth Secretary-General Patricia Scotland said the latest emissions report reveals countries are not on track to meet the Paris Agreement goals because of the collective failure to reduce greenhouse gas emissions.
